'Harry Potter and the Deathly Hallows Part I' NYC Premiere Red Carpet

Lined with 'Potter' posters and screaming, costumed fans, the carpet outside Lincoln Center was a spellbinding zoo, as the stars of the beloved franchise joined excited celebrities and this installment's director, David Yates, for a screening of the much-anticipated film.

The series' penultimate film is an emotional one and "quite heavy," according to Yates, who said author JK Rowling expressed that she loved the film. Watson said the film was "dark and pretty scary," and that it made her cry.

Our Slytherin scarf caught Felton's attention: He told Moviefone that he was happy to see someone representing Draco's house -- as most fans outside were adorned in Gryffindor attire.

Grint said he's looking forward to moving on to different films after 10 years of 'Potter,' while Radcliffe said fans of the book will be happy with how faithful the two-part adaptation of the series' finale is.

"It's been an amazing 10 years and you can't just carry on doing it forever," Radcliffe said.
